During the travelling montage, Po and his father endure on their way to the secret panda village, they pass by two large stones that sit on an equally stone-like terrain, and are slanted toward the right of the screen. Shrek and Donkey pass by these same stones on their way to Fiona's castle in Shrek (2001).
In order to get a feel for how pandas live, the filmmakers went directly to China's biggest panda preserve in Chengdu. While there, the filmmakers noted that pandas rolled to get places, and incorporated that into this movie.
The jombies were animated to skip some frames throughout their movements to be in direct contrast to the living Masters, who are more fluid in movements.
Four of Angelina Jolie's children, Shiloh Jolie-Pitt, Pax Jolie-Pitt, Knox Jolie-Pitt, and Zahara Jolie-Pitt, are voice extras when Po talks to the pandas about a game plan.
The CEO of DreamWorks confirmed that this is not the last movie in the franchise, and that three more Kung Fu Panda movies are planned.
